Abstract
［Objective］ To investigate the effects of steam explosion pretreatment on the microstructure of oats,the content of β-glucan,the digestion characteristics of starch,and its effect on obesity in mice fed a high -fat diet.［Methods］ The effects of steam explosion treatment under different pressures (0.3,0.5 MPa ) and time (30,60,90 s) on the microstructure of oats and the composition of β-glucan are investigated,and the obesity inhibitory effect of steam -exploded oats in a simulated high -fat diet environment is studied.［Results］ Steam explosion can destroy the ordered structure of the oat cell wall,increase the content of slowly digestible starch,the content and dissolution rate of water -soluble β-glucan,and reduce the content of resistant starch.It is positively correlated with the intensity of the steam explosion.At 0.5 MPa,the content and dissolution rate of water -soluble β-glucan are the highest.The intervention of steam -exploded oats in mice fed a high -fat diet can reduce the body weight gain of these mice.Compared with the high -fat diet group,the highest reduction in body weight can reach 10.5%,and it can also reduce fat deposition in the liver.［Conclusion］ Steam explosion can optimize the microstructure of oats,increase the content of water -soluble β-glucan,improve the digestion characteristics of starch,and significantly inhibit obesity in mice induced by a high -fat diet.
